Abstract: rlncBT,a P2P content distribution system based on random linear network coding is presented.The system design is based on the principles and techniques of network coding and BT,and wherein improves the policy of Piece selection.Experimental simulation results and theoretical analysis show that rlncBT has the following advantages:higher success ratio of downloading,shorter average downloading time,better robustness,efficient utilization of network and server resources and less dependency on the server and seeds.

Key words: content distribution, file sharing, random linear network coding, P2P

摘要: 基于线性编码和BT的原理和技术,设计和实现了一个基于随机线性网络编码的P2P内容分发系统,并对Piece选择策略进行了改进。通过仿真实验和理论分析,表明该系统具备下载成功率更高、平均下载时间更短、更好的健壮性、对网络带宽资源与服务器资源的利用率更高、对种子节点和服务器的依赖性更弱等多项优点。
